yesagonistic

I wonder whether, in the choice of title, the band was referring to an older meaning of the word "science." Our current meaning only dates to the late Renaissance. Previously, the word simply meant any branch of knowledge, including the study of the divine.

Yes do not "teach us" anything. Their songs may address certain themes, though the obscurity of many of Anderson's lyrics often, and to my mind fortunately, makes any pedagogical function unlikely. These guys are musicians. While their music may at times take on a philosophical stance, the stance does not define, and most certainly does not subordinate, the music. Where such subordination occurs, as on some of the studio track son Keys to Ascension, it invariably undermines the music.

Actually, Reggy, "agnostic" is the opposite of "gnostic" and means simply "not knowing," referring specifically to the unknowability of anything outside of the material realm. To be an agnostic is to admit that on does not, and cannot, know anything beyond what the senses can perceive. There is nothing about agnosticism that necessarily implies nature worship, or "love" of anything at all. Agnostics are simply people who admit that they do not and cannot know God / the gods, or even whether such entities exist. This is not necessarily a spiritual position, spirit itself being arguably unknowable, and Jon Anderson is a deeply--and eccumenically--spiritual person.
